Singer Rihanna may not be able to sing a lick, but she sure knows how to put up a fight!

The pop entertainer is countersuing her former personal trainer Cindy Percival for $26,244.63 in unpaid fees and travel expenses. Back in March, Cindy filed a lawsuit against Rihanna for $26,144.14 in upaid wages. According to the personal trainer, Rihanna never paid for the $1500 a day personal training services she was hired to perform between September and October of 2009.

However, “Rude Boy” Rihanna isn’t taking these accusations too kindly and is ready to give Cindy a round for her money. In her version of the story, Cindy was paid up front for services she failed to provide or pay back for.

But either way it goes, somebody needs to be sued for those singing lessons Rihanna was given. Or the lack thereof. Geez! (LOL)
